Can Rachman’s indirect pathways be used to un-learn fear? A prospective paradigm to test whether children’s fears can be reduced using positive information and modelling a non-anxious response

This study investigated whether children’s fears could be un-learned using Rachman’s indirect pathways for learning fear. We hypothesised that positive information and modelling a non-anxious response are effective methods of un-learning fears acquired through verbal information. One hundred and seven children aged 6–8 years received negative information about one animal and no information about another. Fear beliefs and behavioural avoidance were measured. Children were randomised to receive positive verbal information, modelling, or a control task. Fear beliefs and behavioural avoidance were measured again. Positive information and modelling led to lower fear beliefs and behavioural avoidance than the control condition. Positive information was more effective than modelling in reducing fear beliefs and both methods significantly reduced behavioural avoidance. The results support Rachman’s indirect pathways as viable fear un-learning pathways and supports associative learning theories.

Aging is associated with positive responding to neutral information but reduced recovery from negative information

Studies on aging and emotion suggest an increase in reported positive affect, a processing bias of positive over negative information, as well as increasingly adaptive regulation in response to negative events with advancing age. These findings imply that older individuals evaluate information differently, resulting in lowered reactivity to, and/or faster recovery from, negative information, while maintaining more positive responding to positive information. We examined this hypothesis in an ongoing study on Midlife in the US (MIDUS II) where emotional reactivity and recovery were assessed in a large number of respondents (N = 159) from a wide age range (36–84 years). We recorded eye-blink startle magnitudes and corrugator activity during and after the presentation of positive, neutral and negative pictures. The most robust age effect was found in response to neutral stimuli, where increasing age is associated with a decreased corrugator and eyeblink startle response to neutral stimuli. These data suggest that an age-related positivity effect does not essentially alter the response to emotion-laden information, but is reflected in a more positive interpretation of affectively ambiguous information. Furthermore, older women showed reduced corrugator recovery from negative pictures relative to the younger women and men, suggesting that an age-related prioritization of well-being is not necessarily reflected in adaptive regulation of negative affect.

A sword with two edges: propagation studies on both positive and negative information in online social networks

Online social networks (OSN) have become one of the major platforms for people to exchange information. Both positive information (e.g., ideas, news and opinions) and negative information (e.g., rumors and gossips) spreading in social media can greatly influence our lives. Previously, researchers have proposed models to understand their propagation dynamics. However, those were merely simulations in nature and only focused on the spread of one type of information. Due to the human-related factors involved, simultaneous spread of negative and positive information cannot be thought of the superposition of two independent propagations. In order to fix these deficiencies, we propose an analytical model which is built stochastically from a node level up. It can present the temporal dynamics of spread such as the time people check newly arrived messages or forward them. Moreover, it is capable of capturing people's behavioral differences in preferring what to believe or disbelieve. We studied the social parameters impact on propagation using this model. We found that some factors such as people's preference and the injection time of the opposing information are critical to the propagation but some others such as the hearsay forwarding intention have little impact on it. The extensive simulations conducted on the real topologies confirm the high accuracy of our model.

Whole-brain functional connectivity during emotional word classification in medication-free Major Depressive Disorder: abnormal salience circuitry and relations to positive emotionality

Major Depressive Disorder (MDD) has been associated with biased processing and abnormal regulation of negative and positive information, which may result from compromised coordinated activity of prefrontal and subcortical brain regions involved in evaluating emotional information. We tested whether patients with MDD show distributed changes in functional connectivity with a set of independently derived brain networks that have shown high correspondence with different task demands, including stimulus salience and emotional processing. We further explored if connectivity during emotional word processing related to the tendency to engage in positive or negative emotional states. In this study, 25 medication-free MDD patients without current or past comorbidity and matched controls (n=25) performed an emotional word-evaluation task during functional MRI. Using a dual regression approach, individual spatial connectivity maps representing each subject’s connectivity with each standard network were used to evaluate between-group differences and effects of positive and negative emotionality (extraversion and neuroticism, respectively, as measured with the NEO-FFI). Results showed decreased functional connectivity of the medial prefrontal cortex, ventrolateral prefrontal cortex, and ventral striatum with the fronto-opercular salience network in MDD patients compared to controls. In patients, abnormal connectivity was related to extraversion, but not neuroticism. These results confirm the hypothesis of a relative (para)limbic-cortical decoupling that may explain dysregulated affect in MDD. As connectivity of these regions with the salience network was related to extraversion, but not to general depression severity or negative emotionality, dysfunction of this network may be responsible for the failure to sustain engagement in rewarding behavior.

The impact of online reviews on hotel booking intentions and trust

A growing reliance on the Internet as an information source when making choices about tourism products raises the need for more research into electronic word of mouth. Within a hotel context, this study explores the role of four key factors that influence perceptions of trust and consumer choice. An experimental design is used to investigate four independent variables: the target of the review (core or interpersonal); overall valence of a set of reviews (positive or negative); framing of reviews (what comes first: negative or positive information); and whether or not a consumer generated numerical rating is provided together with the written text. Consumers seem to be more influenced by early negative information, especially when the overall set of reviews is negative. However, positively framed information together with numerical rating details increases both booking intentions and consumer trust. The results suggest that consumers tend to rely on easy-to-process information, when evaluating a hotel based upon reviews. Higher levels of trust are also evident when a positively framed set of reviews focused on interpersonal service.

Masturbation and the media

This paper explores the important role the media play in informing young people about masturbation. A pilot study of focus groups with twenty-two young Australians, aged between 14-16 explored what they know about sex and sexuality, and where they have found that knowledge. This paper reports on their knowledge about masturbation. Although researchers agree that masturbation can be a positive part of healthy sexual development, most young people reported that they received very little positive information about it from their parents or in formal sex education in school. These young people’s discussions around this topic were largely ambivalent, but also highly complex due to the varying levels and types of information that they receive. In this context the media play a vital role in providing information about masturbation through books and magazines for young women, and television comedies for young men.

The use of non-hypothetical experimental markets for measuring the acceptance of genetically modified foods

The findings from a study measuring consumer acceptance of genetically modified (GM) foods are presented. The empirical data were collected in an experimental market, an approach used extensively in experimental economics for measuring the monetary value of goods. The approach has several advantages over standard approaches used in sensory and marketing research (e.g., surveys and focus groups) because of its non-hypothetical nature and the realism introduced by using real goods, real money, and market discipline. In each of three US locations, we elicited the monetary compensation consumers required to consume a GM food. Providing positive information about the benefits of GM food production, in some cases, reduced the level of monetary compensation demanded to consume the GM food. (C) 2004 Elsevier Ltd.

Cadastro positivo: a possibilidade de acesso ao crédito como um dos caminhos para o desenvolvimento social

A presente dissertação objetiva demonstrar que o Cadastro Positivo, como instrumento que permite o aumento do acesso ao crédito, pode ser considerado um dos fatores a proporcionar o desenvolvimento social. Nesse sentido, apresentaremos as posições que norteiam o instituto da privacidade como direito fundamental e como “valor intermediário”, tudo considerando o contexto dos bancos de dados de proteção ao crédito. Apresentaremos, ainda, dados obtidos em pesquisa que buscou conhecer as impressões dos consumidores da cidade do Rio de Janeiro em relação à criação Cadastro Positivo, bem como buscou verificar o nível de preferência desses consumidores em relação à possibilidade de aumento do acesso ao crédito e a privacidade, tendo em vista os limites jurídicos impostos ao tratamento das informações positivas pelos bancos de dados. Demonstrar-se-á que apesar de o Brasil viver um momento de transformação em relação ao tema por conta da criação da Lei 12.414/11, ainda, existem muitos desafios a serem superados por conta da nossa estrutura jurídica e costume social.

An essay on impression management: three randomized experiments with financial analysts

This thesis aims to explore the concept of impression management from the financial analysts’ point of view. Impression management is the definition of the act of an agent manipulating an impression that another person have of this agent, in the context of this thesis it happens when a company make graphics to disclosure financial-accounting information in order to manipulate the market’s perception of their performance. Three types of impression management were analyzed: presentation enhancement (color manipulation), measurement distortion (scale manipulation) and selectivity (the disclosure of positive information only). While presentation enhancement improved only the most impulsive financial analysts’ perception of firm’s performance, the measurement distortion improved the perception of performance for both groups of financial analysts (impulsive and reflective). Finally, selectivity improved the financial analysts’ perception of firm’s performance for both groups (impulsive and reflective), although impulsive financial analysts assigned lower ratings when compared to their reflective peers, on average, to a hypothetical company.

Overview on the performance of Brazilian broilers (1990 to 2009)

This article describes the genetic evolution of commercial broilers between 1990 and 2009, considering live performance, in particular, in terms of weight gain and feed conversion ratio. In order to determine if the assumption that the relationship between body weight gain and feed conversion ratio is increasing and positive, information on all broiler strains reared in Brazil were collected from several companies present in five Brazilian regions. This survey aimed at evaluating broiler live performance as a function of genetic improvement with time. Broiler performance improved, as shown by the statistical differences obtained for the following parameters: livability, live weight, daily weight gain, feed conversion ratio, and production efficiency index between 1990 and 2009. However, live weight gain and feed conversion ratio are emphasized due to the significant differences found along the studied period.

JORNAL-LABORATÓRIO, UMA ATIVIDADE PEDAGÓGICA MUITO ALÉM DO EXERCÍCIO DE MARKETING

A relação entre jornal-laboratório e marketing das instituições de ensino superior é analisada no trabalho. Valendo-se do estudo de casos múltiplos, são comparados impressos laboratoriais, reconhecidos no meio acadêmico pelo valor pedagógico do exercício proporcionado aos alunos, com aqueles que circulam como ¬house-organs¬, trazendo informações positivas das respectivas faculdades. Eles são examinados com base nos conceitos de ensino de jornalismo e de marketing, especialmente para instituições educacionais. O objetivo é demonstrar que jornais-laboratório transformados em jornais de empresa, no intuito de atender a necessidades de comunicação das instituições com o mercado, contrariam o que é preconizado pelo ensino de jornalismo e pelo próprio marketing. É possível perceber que impressos laboratoriais que simulam a realidade da profissão, com o propósito pedagógico, estão mais adequados como produto ao mix de comunicação porque levam o estudante, como consumidor, a vivenciar situações marcantes de aprendizado, conforme estabelece o marketing de experiências para levar clientes à lealdade com as organizações.(AU)
